+Subject: [PATCH] backlight: Avoid restoring brightness to an unreadably dim
+ level
+
+Some systems turn the backlight all the way off at the lowest levels.
+Clamp saved brightness to at least 1 or 5% of max_brightness.  This
+avoids preserving an unreadably dim screen, which would otherwise force
+the user to disable state restoration.

+Subject: [PATCH] backlight: do nothing if max_brightness is 0
+
+On virtually any newer Asus mainboard, the eeepc-wmi driver is loaded.
+It exposes a backlight device despite the lack of any physical backlight
+devices. This fake backlight device has max_brightness set to 0. Since
+the introduction of the clamp_brightness function, systemd-backlight
+tries to write '1' to brightness and fails.
+
+This patch changes systemd-backlight to exit gracefully when
+max_brightness is 0 before performing any action. This affects
+both the load and save actions.

+Subject: [PATCH] job: add waiting jobs to run queue in unit_coldplug
+
+When we have job installed and added to run queue for service which is
+still in dead state and systemd initiates reload then after reload we
+never add deserialized job to the run queue again. This is caused by
+check in service_coldplug() where we check if deserialized state is
+something else than dead state, which is not the case thus we never call
+service_set_state() and finally unit_notify() where we would have added
+job to the run queue.
+
+Thanks to Michal Sekletar <msekleta@redhat.com> for the original patch.
